Mac Pro Mid-2010 Westmere
Some highlights from reviews:
*Intel Core i7-980X 6-Core CPU*
by Olin Coles
http://benchmarkreviews.com
*Intel HD Boost*
full SSE4 instruction set, improves multimedia and compute-intensive applications.
128-bit SSE instructions one per clock cycle, SSE4-optimized applications.
Gulftown supports existing Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and Streaming SIMD Extensions 4 (SSE4).
Transcoding
Core i7-920 (2.66) 15129 point baseline
Gulftown Core i7-980X 29% performance
*File compression* CPU Zip library tests, improves archiving process by nearly 81% compared to quad core 2.66 with eight threads.
*AES Encryption* test boosts performance 1945%
With 2 cores disabled, the 980X outperformed the i7-920 by 1572%
Cinebench CPU mult-threaded test
Core i7-920 2.66GHz score 4.29
i7-980X Extreme 3.33GHz Gulftown score 7.95
theoretical score 6.44
- six cores operating at 2.66GHz
Based on the benchmarks of professional productivity application,s performance for engineering and design of about 13%
PCMark Vantage +TV and Movies benchmark+, Gulftown outperforms the i7-920 by nearly 15%
*Queen and Photoworxx* are synthetic benchmarks that operate the function many times over and over-exaggerate by several magnitudes what the real-world performance would be like.
The Queen benchmark focuses on the branch prediction capabilities and misprediction penalties of the CPU. It does this by finding possible solutions to the classic queen problem on a chessboard.
At the same clock speed theoretically the processor with the shorter pipeline and smaller misprediction penalties will attain higher benchmark scores.
*Gulftown shows a 136% increase in raw processing power.*
*CPU PhotoWorxx*
Gulftown 6-Core past 4-core i7-920 by 39%
+Gulftown didn't create any conspicuous benefits to *video game performance*, it didn't harm frame rate, either.+
Westmere microarchitecture reduces power drain down to only 12W at idle.
Single threaded performance for Westmere is almost identical to Nehalem. However, multi-threaded performance increases by 20-42% for the extra 2 cores. Westmere is a solid improvement for multithreaded workloads at the same power level as the previous generation. Realworldtech: Westmere Performance and Westmere Arrives
